The bitcoin blockchain was supposed to split into two blockchains in roughly 8 days. But it looks like SegWit2x backers couldn’t convince enough people in the bitcoin community to make the SegWit2x blockchain the new mainstream bitcoin blockchain.

The organizers of a controversial bitcoin scaling proposal are suspending an attempt to increase the block size by way of a software upgrade.

Known for its strong early support from bitcoin startups and mining pools, the plan, called Segwit2x, or simply 2x, was to trigger a block size increase at block 494784, expected to occur on or around November 16th.

The suspension was announced today in an email, written by Mike Belshe, CEO and co-founder of bitcoin wallet software provider BitGo. One of the leaders of the Segwit2x project, he argued that the scaling proposal is too controversial to move forward.

He wrote:

“Unfortunately, it is clear that we have not built sufficient consensus for
a clean block size upgrade at this time. Continuing on the current path could divide the community and be a setback to Bitcoin’s growth. This was never the goal of Segwit2x.”

“Until then, we are suspending our plans for the upcoming 2MB upgrade,” he added.

The note is also signed by companies that originally supported the plan, forged at an in-person meeting in May, including CEO and co-founder Mike Belshe, Xapo CEO Wences Casares, mining pool Bitmain co-founder Jihan Wu, Bloq CEO and co-founder Jeff Garzik, Blockchain CEO and co-founder Peter Smith and Shapeshift CEO and founder Erik Voorhees.
